Title: Improved method for recovering oil from whales or other sea-mammals
IPC: C11B1/00
Filed: 1949-08-18
Abstract: Oil is obtained from whales or other sea mammals by digesting the bones (or other parts which give an alkaline residue on digestion) in the presence of an acidic residue obtained by the previous digestion of the flesh or blubber (or other parts which give an acidic residue on digestion).  Sufficient of the acidic residue is employed for the new residue to be neutral or slightly acid, thereby avoiding the formation of stable oil emulsions. The acidic residue may be added prior to or during the digestion and may be received either direct from an oil separator, before or after de-oiling, or from a storage tank.  The digestion is carried out in a rotating boiler drum at elevated temperature and pressure and, following the digestion, the liberated oil is separated. Specification 685,123 is referred to. The Specification as open to inspection under Sect. 91, refers to the digestion of the bones (or other parts which give an alkaline residue on digestion) in the presence of the raw flesh or blubber (or other parts which give an acidic residue on digestion).

Title: Improvements in or relating to the starting, stopping and reversing of internal combustion engines of the diesel or compression ignition type
IPC: F01L13/00
Filed: 1935-07-31
Abstract: 460,592. Starting, stopping, and reversing; relief valves. DALE, C. B. M., and PETTERS, Ltd. July 31, 1935, No. 21765. [Classes 7 (ii) and 7 (v)] In a mechanism for controlling the starting, braking, reversal, and stopping of an engine of the Diesel or compression-ignition type, a relief valve 4 on each engine cylinder 1 is loaded by a spring 21, Fig. 2, acting directly upon the valve stem 27, and by a spring 20 acting upon a piston 24 movable in a cylinder and adapted to engage the valve stem 27. On the admission of compressed air beneath the piston 24, the latter is forced against a stop 25 and the valve stem is relieved of the load imparted by the spring 20 and opens at a lower or adjustable pressure for braking purposes. As shown, the mechanism is controlled by means of a shaft 5 provided with a hand wheel 6 and carrying cams 7-9 for the actuation of valves 10.. 12 in the air-supply system and a scroll cam 17 acting through linkage 17x and a rock shaft 16 on the fuel supply 40 and the compressed-air supply valve 13. In the starting ' position of the control shaft 5, the valve 10 is opened to admit air from a compressed-air receiver 14 to the valve 13, which is operated by cams on the shaft 15 to supply air to operate the starting valves 3 on the engine cylinders. The shaft 5 is then turned to the normal running' position, in which starting air is cut off and the fuel-supply device 40 is actuated by cams on the shaft 15. For reversing, the shaft 5 is first turned to a ' braking ' position, closing the valve 12 which normally connects the relief valve 4 to the atmosphere, and opening the valve 11 connecting it to the air receiver 14 ; the fuelsupply device 40 is also cut off and the starting- air valve 13 is brought into action. Air is admitted to the cylinder 1 when the piston is near the bottom of its stroke and is compressed and forced through the relief valve 4 back to the receiver 14, producing a braking effect. During the braking operation, compressed air is admitted by the pipe 22 and a branch pipe 23 beneath the piston 24 acting on the stem of the relief valve, which is thus enabled to open at a lower pressure. When the engine has been stopped, the shaft 5 can be turned to the reverse starting ' position. In order to prevent the shaft 5 from turning beyond the ' starting ' position until starting in the required direction has been effected, an interlocking device comprises an oil pump 29, Fig. 3, which may also serve to supply lubricant to the engine. The pump is preferably a gear pump and is provided with valves 30, 31 so that it delivers oil in the same direction irrespective of the direction of rotation. Suction pipes 32, 33 are connected to cylinders 34, 35 fitted with plungers 37, 38 co-operating with a projection 36 on the control shaft 5. When the engine starts, one or other plunger 37 or 38 is withdrawn by suction and allows the further turning of the shaft 5.
